I love fresh fruit. I love fruit on skewers. What I do not love is knowing that on the way to the cute little pineapple, someone's unwashed hand brushed against the wet melon that I might have eaten, were I so inclined. I find the idea of such handled food so nasty that I actually feel queasy when I see one of those edible arrangements at a party. I can't be the only one.
And yes, it is different from other people handling dry things, like chips or canapes, at least in my head. It's the wetness factor that icks me.
